With guns drawn, officers ordered four people out of a home near where Dixon's body was found. Detectives Monday afternoon were interviewing the men, but are only calling them persons of interest and not suspects.

"Detectives are talking to several persons of interest, but we have not identified a suspect at this time," said Sgt. Melissa Jaques.

A Port St. Lucie Police K-9 unit led officers to the home where those four men were staying. At least one of the men was released from police custody just after 5 p.m.
